bleeding: all surgery carries a risk of bleeding. This may be a persistent oozing that requires surgical correction or the blood may collect beneath the surface as a hematoma.
hematoma: when blood collects beneath the skin it is called a hematoma. A small hematoma may absorb on its own but a large one is cosmetically unacceptable and requires surgery. A hematoma may also cause increased scarring and contracture of the capsule around the implant. A hematoma is also an excellent medium for the growth of bacteria and increases the risk of infection.
seroma: sometimes serum will collect around the implant. This may need removal with a needle or even surgical drainage.
infection: all surgery carries and risk of infection of this happens the implant may need to be removed. Antibiotics are often given to reduce the risk of infection.
swelling: the chin will be swollen for several weeks after surgery and the final result cannot be seen for at least a month.
bruising: some bruising is normal but if there is increased bleeding the bruises can be significant and extend on to the neck.
implant displacement: the surgeon tries to make the pocket and the implant about the same size, but if the pocket is larger than the implant the position can change.
asymmetry: if the implant is not completely in the midline it will appear asymmetrical.
mobililty: if the pocket is too large the implant will move around.
extrusion: the implant can work its way through the incision and appear at the surface.
nerve damage: numbness and discomfort can occur due to damage to the nerves in the area.
bone erosion: pressure of the implant on the underlying bone can cause thinning of the bone.
